Gaming- Favorite Games, etc.

Consider this topic to be a thread focused on your favorite games--feel free to list your favorite games, to talk about why they're so great, and to list any experiences you've had with the title that would supplement its overall greatness.

Personally some of my favorite games would have to be Chrono Trigger, the Sonic series, the Elder Scrolls series, and to keep it in the vein of classic games, I'll go with StarTropics and Crysalis for NES, DOOM & Diablo for PC, and I just have to put Zelda 64: Ocarina of Time on here because it pwns so much ass.
